Biology Practice Exam 3 In a population of wild flower, there is this frequency of flower color alleles: R (red, dominant) = 0.8, r (white, recessive) = 0.2. Which describes how the r allele might be eliminated if only a few individuals from each generation reproduce? (a) the Hardy-Weinberg theorem (b) punctuated equilibrium (c) sympatric speciation (d) altruism *(e) genetic drift The term "allopatric" was used in the context of (a) whether symbiosis benefits both parties. *(b) the formation of new species when the parent population becomes geographically isolated. (c) whether the organism provides its own nutrition or needs to feed on others. (d) whether the organism requires O2. (e) whether evolution was gradual or sudden. When structures in two different species are evolved from a common ancestor, this is an example of *(a) homology. (b) coevolution. (c) convergent evolution. (d) sexual selection. (e) altruism. Suppose that the red flower allele is dominant to the white flower allele and that the frequency of the red allele in the population is 0.8 while the frequency of the white flower allele is 0.2. What proportion of plants will have red flowers? (a) 0.2
